The Copperado-A6 occurrence is situated southeast of Highway 5, north of Nicola Lake and approximately 23 kilometres northeast of Merritt.
Upper Triassic Nicola Group volcanic rocks are cut by granodiorite and granite of the Lower Jurassic Nicola batholith. A slightly copper-stained quartz-feldspar pegmatite zone in foliated granodiorite contains scattered radioactive allanite. A sample of the pegmatite assayed 0.0017 per cent equivalent uranium.
The Turlight copper deposit (MINFILE 092SIE055) situated to the southwest was discovered in 1928. An 18-metre-deep shaft was excavated to follow a prospective quartz vein. After many years of inactivity, Guichon Mine Limited acquired the property and put it back into production in 1947. From 1947 to 1948, the property was held under option by Anaconda Copper Mining Company. In total, seven drillholes totalling 786 metres were completed before Anaconda dropped the option on the property. Guichon Mine Limited continued production until 1951. At the end of production, six levels had been established along the 137-metre-deep shaft. Between 1948 and 1951, approximately 136 to 181 tonnes of ore grading 5 per cent copper were shipped to the smelter at Tacoma (Assessment Report 10518, page 2).
In 1956, Western Copperado Mining Corporation took control of the Turlight mine, dewatered the shaft and drilled approximately 609 metres on the 61-metre (200-foot) level. That year, approximately 41 tonnes of ore grading 6.91 per cent copper were shipped to the Tacoma smelter.
The following year, Shield Mining Surveys Limited completed a geophysical survey and 20 diamond drill holes totalling 3036 metres. A short adit and several short drill holes were completed on a mineralized zone approximately 1.6 kilometres north of the Turlight shaft.
Toluma Mining and Development Limited optioned the property in 1960 and conducted work programs until 1963. Work included geophysical surveying, geochemical surveying and bulldozer trenching. Encouraging molybdenum and copper results were encountered in the Southeast zone (MINFILEs 092ISE124, 092ISE125), along with encouraging copper results in the Northwest zone (MINFILE 092SIE123). Six diamond drill holes completed in the Southeast zone between 1961 and 1962 assayed low-grade copper-molybdenum-silver values.
In 1965, Rio Tinto Canadian Exploration Limited optioned the property and completed a magnetometer geophysical survey over the Northwest and Southeast zones. The property was then optioned to Great Slave Mines Limited in 1966. In 1967, Great Slave Mines completed magnetometer, photogeological and geochemical studies on the property. Also during this time, a joint provincial and federal government aeromagnetic geophysical survey was flown over the region.
Danstar Mines Limited acquired the Copperado property and dewatered the Turlight shaft again in 1973. This was followed by a program of surveying, geological mapping and sampling. In 1976, Danstar Mines conducted an exploration program consisting of three percussion drill holes totalling 264 metres near the Turlight mine (MINFILE 092ISE055), three percussion drill holes totalling 320 metres at the Copperado-TM 1 occurrence (MINFILE 092ISE125) and an induced polarization–resistivity geophysical survey over a portion of the property including the Turlight mine (MINFILE 092ISE055) and Copperado-P66 occurrence.
From 1981 to 1982, Danstar Mines completed two BQ diamond drill holes totalling 306.76 metres. One hole, drillhole D-5-82, assayed several intersections of anomalous copper results.
The area was later acquired by C.R.C. Explorations Limited as the Cop property. In late 1996, LaMancha Resources Limited optioned the property, established 33.7 kilometres of grid and baseline and collected 1188 soil samples. The following year, exploration consisted of geological mapping, prospecting and rock sampling (184 samples). In 2000, the grid was extended to the north, east and west, followed by a ground magnetometer, very low-frequency electromagnetic geophysical survey and the collection of 484 soil samples and 40 rock samples. An additional 10 kilometres of induced polarization surveying was completed over the West zone.
In 2006, Columbia Yukon Explorations Incorporated optioned the property and completed five BQ diamond drill holes totalling 967.73 metres. Four holes were completed in the West zone (MINFILE 092ISE123) and one in the East zone (MINFILEs 092SIE124, 092ISE125). The East zone drillhole (COP06-05) targeted anomalous copper-silver values in soil and highly anomalous copper-silver-gold rock geochemistry results.
Sometime prior to 2011, the Cop claim area was allowed to lapse and the Peacock property was staked over the area by Christopher Delorme. In 2011, claim owner Delorme retained Terry Garrow to conduct a ground geophysical survey and mineral evaluation on the Peacock property. Delorme followed up in 2012 by conducting a rock and soil sampling program.
